LOWER PROTRUSION. 781
"After the holes were drilled the remainder of the sawing was done
on l)oth sides, and the two small sections of the jaw removed.
" Soft copper wire ligatures were now passed through the holes from
the external surface. These were crossed on the internal surface, grasped
with a pair of pliers, and twisted until the several parts were drawn
together at the lower border, forming an apparently close and smooth
abutment of the opposing ends.
" The copper wire ligatures proved ineffectual, so clamp bands,
with buccal tubes, were applied to the molar and bicuspid on one side,
and to the molar and canine on the other, and traction screws ex-
tended through the tubes. By tightening the nuts on these screws the
parts of the jaws were brought again in contact. As an additional pre-
caution, ' bicuspid fracture bands ' were placed on the first upper and
second lower bicuspid.

"A figure-8 ligature of brass wire was adjusted to the little knobs
on these bands, and the rear fragment was firmly ligated to the upper
jaw. All the various parts were held absolutely without change for
five weeks. The patient lived on liquid food and suifered no great in-
convenience physically.
"A four-tailed plaster bandage was adjusted and retained without
change for four weeks."
Within eight or nine weeks the ap]>Hances were removed from both
sides, osseous union having taken place. Subsequently some of the
posterior teeth were lengthened by means of gold crowns, and the
occlusion restored. The final result is shown in Fio;. 791.
There was "an entire loss of sensation in the lower lip, caused by
cutting the sensory parts of the inferior dental nerve.
"The pulps of the middle part of the jaw do not seem to have been
affected at all.
